🦘 Jump into the repositories (git, mercurial…) of your filesystem with telescope.nvim, without any setup
Hi, it’s Clément! 👋
I’m currently working as a software engineer at Cloudflare in London, where I get to work with exciting technologies like eBPF or Rust. Previously, I worked on non-intrusive performance analysis at the SnT, a lab part of the University of Luxembourg.On my spare time, I enjoy writing and contributing to open-source programs. Most of that activity is visible on GitHub and Stackoverflow. I blog mainly about performance and tools I use (like NeoVim, Hugo or SQLite). Some pages made it to the front page of HackerNews or Lobsters, sparking fruitful discussions in the comments.

Rust Default Values for Maintainability
TL;DR The Default trait can enhance the maintenability of your code. Default values for common types are listed at the end. A PR Review Recently, while reviewing a PR1, I noticed that part of the patch was introducing a new field to a struct: 1diff --git a/src/lib.rs b/src/lib.rs 2index eba9a3a..8619e06 100644 3--- a/src/lib.rs 4+++ b/src/lib.rs [email protected]@ -106,8 +108,9 @@ use std::{ 6 #[derive(Debug, PartialEq, Clone)] 7 pub struct M<'u> { 8 up: &'u str, 9 down: Option<&'u str>, 10+ foreign_key_check: bool, 11 } 12 13 impl<'u> M<'u> { [email protected]@ -137,8 +140,9 @@ impl<'u> M<'u> { 15 pub const fn up(sql: &'u str) -> Self { 16 Self { 17 up: sql, 18 down: None, 19+ foreign_key_check: false, 20 } 21 } That prompted me to reflect on the code I had initially written....
From UltiSnips to LuaSnip
TL;DR LuaSnip is fast and doesn’t have to be complicated. Give it a try! Even if that article shows how LuaSnip shines, I have great respect for the work that has gone into UltiSnips. It is still a reliable, reasonably fast plugin given the constraint it operates in (in particular, Vim compatibility requires a fair amount of Vimscript). I’ve written this article shortly after trying LuaSnip and I’m still very much evaluating it....
You “Own” 16 Milion+ IPv4 Addresses!
TLDR For the foreseeable future, you can likely use 127.0.0.0/8 freely (or at least 127.0.0.0/16). Introducing 127.0.0.0/8, the Loopback Range Visualization of the 127.0.0.0/8 range, from cidr.xyz by Yuval Adam If you have ever done web development or otherwise set up a local server, you have most likely used the IP address 127.0.0.1 to communicate with a local server. Often, localhost is even internally translated to that address....
